taylor Posted September 10, 2011 Report Share Posted September 10, 2011 i know of only 1 guy using it in the shehane and having good success ,its good for the stright 284 as you need it to get up to 2950 fps but the shehane will get thier with h4350 or h4831sc ,you will easy sell it if it dont work theres quite a few straight 284 shooters on the league i am not saying it wont work but i tried in every barrel i have and it aint worked in any of them ,it gives ok accuaracy but it aint hammering like h4831sc its the best out of all the powders i have tested Link to comment Share on other sites More sharing options...
6mmBR Posted September 10, 2011 Report Share Posted September 10, 2011 I've just finished testing fireformed Shehane brass with both 4831SC and Rel 17. With reloader 17 the velocities were impressive 3070 fps with 55 grains. Problem was ES were a bit erratic with one or 2 shots per string going way out. 4831SC was a lot more uniform and the worst ES I got was 15 fps. In the end I opted for a charge of 58 grains with a 180 Berger which gave a velocity of 2930 fps with an ES of 10 fps. Will try it at Diggle.

6mmBR Posted September 10, 2011 Report Share Posted September 10, 2011 Grant, how did you find the temperature sensitivity of 4831sc? My load was developed on a cool day of 14 degrees, obviously this time of the year it shouldn't be a problem. On a warm/hot day to velocities increase much and would the load need to be reduced?

6mmBR Posted September 10, 2011 Report Share Posted September 10, 2011 When is Spudzilla due Mark. When you develope fireforming loads I found 56.5 grains of 4831SC was good. What bullets have you got. I'm using up some 180 hunting VLD's but just had a delivery of some Hybrids which I will try after Diggle. By the way does anyone know where they like to be in relation to the lands? I was thinking of a jump of .015" Cheers Dave Link to comment Share on other sites More sharing options...

1967spud Posted September 10, 2011 Author Report Share Posted September 10, 2011 Neil is having a look at my weapon on monday . And hopefully he'll build the gun at the same time i think. I will be fire forming with 52 g r17 for two reasons 1. to use up some r17 and secondly to save on the 4831sc . There is a small chance that isf the r17 doesnt work well fforming ill "cream" the fireforming. The r17 seems to work well in a f forming load and i cant see a reason to use it at that stage. As for bullets ive got a few (2000) vld's here in the 180 g flavour. Which i imagine ill start by touching and then back of a10 thou and see what happens.

6mmBR Posted September 10, 2011 Report Share Posted September 10, 2011 Try 52 grains of Rel 17 as a fireforming load,its one Bill Shehane recommends, it gave 2920 fps in my gun with ok accuracy ES was around 35. However that was the match load in my old straight .284 and it ran an ES of 15 and propelled a 175 SMK @ 2970 fps. Cheers Dave Link to comment Share on other sites More sharing options...
